Before making connections to the input or output terminals of the product, ensure that the product is properly grounded.

Ground the Product. The modules are indirectly grounded through the grounding conductor of the mainframe power cord. To avoid electric shock, the grounding conductor must be connected to earth ground. Before making connections to the input or output terminals of the product, ensure that the product is properly grounded.

Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings and markings on the product. Consult the product manual for further ratings information before making connections to the product.

Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal.

Do Not Operate Without Covers. Do not operate this product with covers or panels removed.

Use Proper Fuse. Use only the fuse type and rating specified for this product.

Avoid Exposed Circuitry. Do not touch exposed connections and components

when power is present.

Wear Eye Protection. Wear eye protection if exposure to high-intensity rays or laser radiation exists.

Preface

Manual Structure

This manual contains the specifications and performance verification procedures for the:

H CSA8000, CSA8000B, and CSA8200 Communications Signal Analyzers

H TDS8000, TDS8000B, and TDS8200 Digital Sampling Oscilloscopes

H Modules that install in the instruments (except the 80A03 module)

NOTE. The 80A03 instruction manual contains its own specifications and servicing information.

Read this preface to learn how this manual is structured, what conventions it uses, and where you can find other information related to this product.

This manual is divided into chapters, which are made up of related subordinate topics. These topics can be cross referenced as sections.

Be sure to read the introductions to all procedures. These introductions provide important information needed to do the service correctly, safely, and efficiently.

Manual Conventions

Modules

Safety

This manual uses certain conventions that you should become familiar with before attempting service.

Throughout this manual, the term module appears. A module is composed of electrical and mechanical assemblies, circuit cards, interconnecting cables, and a user-accessible front panel. References to a module are different than references to products such as “Sampling modules”. “Phase Reference modules”, or “Accessory modules” which are products installed in the instrument compartments.

Symbols and terms related to safety appear in the General Safety Summary found at the beginning of this manual.

Preface

System Specifications

NOTE. This specification is for the instrument; the specifications for the optical, electrical, and other modules that insert in the module compartments of the instrument front panel are included in this chapter of the manual.

This section contains the specifications for the CSA8000, CSA8000B, and CSA8200 Communications Signal Analyzers and the TDS8000, TDS8000B, and TDS8200 Digital Sampling Oscilloscopes.

The 82A04 Phase Reference module affects the CSA8200 and TDS8200 mainframe specifications which are documented in the mainframe specifications. There is no separate specification section for the 82A04 module.

All specifications are guaranteed unless noted as “typical.” Typical specifications are provided for your convenience but are not guaranteed. Specifications that are marked with the n symbol are checked in Performance Verification chapter of this manual.

All specifications apply to the instrument and sampling modules. unless noted otherwise. To meet specifications, these conditions must first be met:

H The instrument must have been calibrated/adjusted at an ambient tempera-

ture between +10 _C and +40 _C.

H The instrument must have been operating continuously for 20 minutes within

the operating temperature range specified.

H The instrument must be in an environment with temperature, altitude,

humidity, and vibration with the operating limits described in these specifications.

NOTE. “Sampling Interface” refers to both the small module compartments and the large module compartments, unless otherwise specified.

Table 1- 4: System - Trigger - Phase correction modes (CSA/TDS8200 with 82A04 Phase Reference module)

Description Characteristics

Note. The specifications in this table apply to a CSA8200 or TDS8200 mainframe equipped with an 82A04 Phase Reference module. The CSA8000, TDS8000, CSA8000B, and TDS8000B mainframes do not support the use of the 82A04 Phase Reference module.

Phase correction capabilities and conditions

A phase reference signal may be applied to a TDS8200 / CSA8200 equipped with the 82A04 Phase Reference module, to provide additional phase information for signals being acquired in Triggered Phase Corrected modes and primary phase information for signals being acqui red in Free Run Phase Corrected modes. For Phase Corrected Triggered modes, the phase correction functionality overlays the functionality of the basic trigger operation, al though restrictions may be imposed.

Number of phase reference module inputs

One per 82A04 module. Up to three 82A04 modules may be inserted in the small compartments of the TDS8200 / CSA8200 and characterized to operate with one or more vertical sampling module(s); only one phase correction module at a time can be used.

Gated Trigger Input -- Enable-to-Acquire Delay

(Option GT equipped mainframes)

3 trigger cycles, where each cycle is defined as (holdoff time + trigger latency). For example:

With holdoff set to its minimum 5 s setting, and a 2.500 GHz clock signal applied to the

External Direct Trigger input (a period of 400 ps), the Enable-to-Acquire delay is approximated

as 3 x (5 s + 0.0004 s) = 15.0012 s.

The Enable-to-Acquire delay is the amount of time after the Gated

Trigger has been enabled (the level goes from TTL LOW to HIGH) when the first valid sample is

retained by the system as the beginning of the waveform record length. When the Gated Trigger

is enabled and triggers begin to occur, the system will reject the first three samples to avoid

system recovery conditions. Once the first three points have been

discarded, then the next vali d trigger cycle will be the first point of the

record section.

Gated Trigger Input -- Maximum Disable Time

(Option GT equipped mainframes)

The system checks the status of the gated Trigger approximately once per holdoff and re-arm

cycle. If the Gated Trigger is disabled immediately after this system check, it will allow nominally

a maximum time of (holdoff + trigger period) to elapsed before the checking for the status of the

Gated Trigger input, recognizing the disable condition, and halting any further sampling of the

signal.
